M.G.
I have one child that rides a regular school bus and we do not tip the driver. My other child is on a special needs school bus and while we do not tip the driver nor the aides we do however make certain to always compliment them throughout the entire year, on a daily basis some days. My "gift" to them is a well-behaved autistic boy, which as any parent knows is a gift in itself. We've been explicitly told not to give out holiday cards.
